By that token one could then also equally argue why did they give the
D78
stock the profile that it has, knowing that it will not fit around the
west
side of the Circle Line, requiring C69/77 stock to be used on District
line
Wimbleware services.

Well quite.

But D78s do fit on the west side of the Circle. They're simply too long for
some of the platforms. Which begs the questions, should they have been built
shorter and reduced the capacity on the main District routes?

Well LU are quite happy to introduce shorter trains that carry less people than
the previous stock (new northern line trains for example) so why not?

Its quite easy to build a number of variations that all have the same
loading
gauge and profile but perhaps different numbers of doors and internal
layout
for the different types of routes they'll run. IMO building a train that
won't
physically fit on a large portion of your network is at best short sighted
and
at worst just plain bloody stupid.


So by your last comment should all stock be tube stock and of a length that
will fit in the shortest platform on the network?

Well obviously not given the huge size difference. But here we're merely
talking about the odd half inch here or there than would make NO difference to
the carrying capacity of the fleet but would have made it far more flexible
operationally. After all , Upminster is just as far out as Amersham from
central london so who's to say the A stock might never have been used on that
route?
